Description

Technical Field

[0001] The utility model relates to the technical field of welding smoke dust removal, in particular to a multi-pipeline dust collector. Background Art

[0002] During welding, metal melts at high temperatures, generating a large amount of fine smoke particles. These particles contain not only metal oxides but also potentially toxic and hazardous gases and oil mist. Prolonged exposure to this environment can increase the risk of occupational diseases such as pneumoconiosis and respiratory problems, and can also cause eye and skin irritation. Furthermore, welding smoke can adhere to equipment and products, affecting their proper operation and the product's appearance.

[0003] Given the harmful effects of welding fume, implementing a dust removal system in welding workstations is essential to ensuring production safety, improving the working environment, and promoting green production. Through scientific layout and efficient filtration technology, this system centrally collects and purifies welding fumes before discharge, effectively reducing their impact on worker health, equipment, and product quality.

[0004] At present, each welding workstation is usually equipped with an independent welding fume collection device, which has low utilization rate and high expenditure cost. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-pipe dust collector, which enables multiple welding workstations to share the same dust removal system through a switching structure, so as to improve equipment utilization and save purchase and maintenance costs.

[0008] A further solution: the snap-on assembly includes a sleeve fixedly connected to the air inlet, a step portion circumferentially arranged on the inner wall of the sleeve, a flange connected to the inner wall of the sleeve, and a buckle provided on the outer wall of the branch pipe; an interlayer cavity for accommodating the buckle is formed between the flange and the step portion; a locking member fixed to the step portion is provided in the interlayer cavity; the flange has at least one opening for the buckle to enter and exit the interlayer cavity.

[0009] A further solution: the number of the openings is two, and they are symmetrically opened on the flange.

[0010] A further solution is that a slot matching the outer contour of the locking piece is provided on one side of the buckle.

[0011] A further solution: also includes a push-clamp structure; the push-clamp structure includes a fixed frame connected to the air inlet of the smoke collection chamber, and a bracket arranged in the fixed frame; the bracket includes an arc-shaped plate and a limiting rod connected to the bottom of the arc-shaped plate; wherein the two extending ends of the arc-shaped plate are connected to the two sides of the fixed frame in an up and down sliding manner; the limiting rod passes through the bottom wall of the fixed frame and is threadedly connected to it.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the present invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0025] See also Figures 1 to 5 In this embodiment, a multi-pipe dust collector includes a dust collector body 1 and a multi-pipe mechanism 2 connected to the dust collector body 1. The multi-pipe mechanism 2 includes a main pipe 21, a switching structure 22, and a branch pipe 23 connected in sequence. The outlet end of the main pipe 21 is connected to the dust collector body 1. The switching structure 22 includes a smoke collection chamber 221, which has an outlet for connecting to the main pipe 21 and a plurality of air inlets connected to the branch pipes 23 in a one-to-one correspondence. The switching structure 22 also includes a clamping assembly 222 disposed within the smoke collection chamber 221 and connected to the outlet end of the branch pipes 23. The branch pipes 23 are connected to the exhaust hood of each welding workstation. Through the switching structure 22, the smoke from multiple welding workstations can be simultaneously drawn into the smoke collection chamber 221, where it enters the dust collector body 1 for treatment before being discharged.

[0026] Furthermore, the snap assembly 222 includes a sleeve 2221, a stepped portion 2222 circumferentially arranged on the inner wall of the sleeve 2221, a flange 2223 connected to the inner wall of the sleeve 2221, and a buckle 231 provided on the outer wall of the branch pipe 23. A sandwich cavity 2224 for accommodating the buckle 231 is formed between the flange 2223 and the stepped portion 2222. A retaining member 2225 is provided in the sandwich cavity 2224, fixedly connected to the stepped portion 2222. The flange 2223 has at least one opening 2226 for allowing the buckle 231 to enter and exit the sandwich cavity 2224. The outer wall of the sleeve 2221 is fixed to the inner wall of the air inlet of the smoke collection chamber 221. A slot 2311 matching the clip 231 is provided on one side of the clip 231. The branch pipe 23 is rotated to make the clip 231 slide from the opening 2226 into the interlayer cavity 2224. The branch pipe 23 is continued to be rotated to make the slot 2311 and the stopper 2225 engage together, so that the branch pipe 23 can be connected to the main pipe 21. The engaging portion is sealed, such as by adhering a sealing layer of a flexible material.

[0027] Furthermore, there are two openings 2226 symmetrically disposed on the flange 2223 .

[0028] Furthermore, the dust collector also includes a push-and-clamp structure 3; the push-and-clamp structure 3 includes a fixed frame 31 connected to the air inlet of the smoke collecting chamber 221, and a bracket 32 disposed within the fixed frame 31; the bracket 32 includes an arc-shaped plate 321 and a limiting rod 322 connected to the bottom of the arc-shaped plate 321; wherein the two extended ends of the arc-shaped plate 321 are connected to the two sides of the fixed frame 31 in an up-and-down sliding manner; the limiting rod 322 passes through the bottom wall of the fixed frame 31 and is threadedly connected thereto. When the branch pipe 23 is clipped and fixed, the arc-shaped plate 321 is pushed upward to lift the branch pipe 23 to prevent the branch pipe 23 from being excessively squeezed at its bend, which would reduce the inner diameter and affect the efficiency of extracting welding smoke. After tightening the limiting rod 322, the position of the arc-shaped plate 321 is fixed.

[0029] Furthermore, the push-and-clamp structure 3 further includes an anti-slip convex portion 33 provided on the inner side of the arc-shaped plate 321. The anti-slip convex portion 33 increases the friction between the arc-shaped plate 321 and the branch pipe 23, further preventing the branch pipe 23 from slipping.

[0030] Furthermore, the dust collector further includes a cover 4 provided on the branch pipe 23, which is used to connect to the exhaust hood of the workstation. In other embodiments, a flow meter and anemometer can also be placed in the cover 4 to monitor the flow rate and flow velocity of the gas entering the branch pipe 23 in real time.

[0031] Furthermore, the dust collector further comprises a proportional valve 5 provided on the branch pipe 23 , and the proportional valve 5 can control the proportional opening of the branch pipe 23 .

[0032] When using the present invention, when it is necessary to simultaneously remove welding fumes from multiple welding workstations, align the buckle 231 at the end of the branch pipe 23 with the air inlet of the smoke collection chamber and insert it. Rotate the branch pipe 23, find the position of the opening 2226, and then continue to push the branch pipe 23 forward. After the end of the branch pipe 23 touches the step 2222, continue to rotate (the outer diameter of the branch pipe 23 is larger than the inner diameter of the step 2222), so that the buckle 231 is locked with the slot 2311. Push the curved plate 321 upward and rotate and tighten the limit rod 322 at the bottom of the curved plate 321. Connect the hood body 4 to the exhaust hood of the corresponding welding workstation, and the dust collector body 1 can be activated to remove dust.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0034] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent modifications made according to the scope of the claims of the present application are within the scope of protection of the claims of the present application.
